` Application illed November 20, 189.9. i Serial No. 737,629. (No model.)

To a/ZZ whom it may concern:

Be it known that I, HENRY STRorHnNKn, a

citizen of the United States, residing at St.

Louis, State of Missouri, have invented certain new and useful Improvements in Barrel- Bungs and I do hereby declare the following to be afull, clear, and exact description of the i invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in barrelbungs; and it consists in the` novel combination and arrangement of parts, as will be hereinafter more specifically described and claimed.

In the drawings, Figure lis a top plan View of my complete invention; and Fig. 2 is a vertical section of the same, taken on the line n: Qc of Fig. l.

The object of my invention is to construct a simple, durable, and practical bung for barrels which will not only hermetically seal the barrel, but is of such a nature that the faucets or vents usually employed in connection with beer barrels or kegs may be readily inserted and forced through the bung, in which operation the diaphragm which seals the bung is readily punctured and operates as a sealing-washer against the escape of the liquid contained within the barrel after the faucet or vent has been forced into position.

Referring to the drawings, l represents a thimble which is provided with exterior screwthreads, by means of which the thimble may be securely fastened within the bung-hole of the barrel, said thimble being provided with an annular flange 2, forming a seat for the re- 'surface of the thimble l is also provided with screw-threads, with which the screw-threads of the collar 6 cooperate, the latter being provided with an annular groove '7, formed on thev lower surface of the same, which surface is adapted to be brought into binding contact with the upperlsurface of the diaphragm 12, a portion of the diaphragm being forced into the annular groove 7 when the parts are in their normal position, whereby the same are hermetically sealed in respect to one another. The collar 6 is provided with an annular extension 8, having an outer inclined wall, over which extension a thin metallic cap 9 is adapted to be sprung, whereby the diaphragm. 12 is thoroughly protected in transit and at other times before the faucet or ventis used in connection with the barrel.

The diaphragm 12 maybe made of any suitable material,or such that can be easily punctured,`and may consist of asbestos, paper, or

any suitable textile material that may answer the purpose and which will form a packing about the faucet or vent when the same are driven through the bn ng. Itis further to be noted that the diaphragm may be formed in any suitable manner best adapted for the purpose, and therefore I do not limit myself to the flat formation as shown.

Having fully described my invention, what I claim is- A barrel-bung, comprising a thimble, an annular :Hange orming apart of the same, and providing a shoulder or seat, a reducingwasher located within said thimble, a suitable washer interposed between the reducing-` Witnesses:
